Users and customers expect sensible and very useful applications in less time. In this competitive market, it is an enormous challenge to develop high performance mobile applications that might meet the expectations of end users. Despite the fact that development of new applications for each mobile operating system in short time is fairly an issue, mobile operating systems vendors are giving their best available resources for creating applications in additional convenient ways. These days, there is a common tendency to look for less complex and quicker solutions that could be used in the process of software development. Developers of a new mobile application have to undertake variety of selections and decisions, including the target platform as well as the development technology to utilize. Mobile application development frameworks contribute in solving this problem. Several frameworks have emerged, which we classify and evaluate their appropriateness. In order to compare existing development frameworks solutions in this research, we compiled a set of criteria to assess mobile application development approaches. In view on these criteria, we evaluated five frameworks that is, PhoneGap, Xamarin, App Inventor, Sencha Touch and DragonRad. For proof of concepts, the chosen framework from the five evaluated mobile development frameworks was used to develop application for water usage management. The research will equip mobile application developers to gain more insight into mobile development frameworks available, therefore helping them to choose the most appropriate framework for their project.

But the diversity of mobile platforms and their APIs increase the effort of software development approach for Smartphone applications. The cross-platform mobile development tool provides code less futures, but they cannot able to solve the device fragmentation issues. The purpose of this paper is to construct a robust architecture of smart phone application development, which should provide an optimal GUI solution (coherency) with the assistance of responsive functionalities. Keywords—cross-platform; mobile applications; coherency; responsive; 1. Introduction applications of these operating systems should download from their respective marketplace. In mobile application Pervasive computing is a technology to access the development process developing the software, building and application at anywhere any time, with the help of any deploymentation should also consider each of its respective device [1]. Everywhere you go, people are using mobile mobile operating systems. So the developer has specialized devices to keep in touch with family and friends, to find a skills in a particular platform, and even though they create nearby restaurant, to store and access the content through an application but it should not compromise with devices the cloud, or to check the latest news headlines.

Mamta Verma Faculty coordinator in Poornima University B.Tech Student in Poornima University Department of Computer Engineering Department of Computer Engineering Poornima University Poornima University Jaipur, Rajasthan Jaipur, Rajasthan Abstract--There are three types of mobile application phones without a significant porting effort since mobile development, which are native mobile application, cross runs in a diverse range of OS. A lot of time money, platform mobile application and hybrid application. Many technologies and man power are needed to diverse mobile devices that runs with different operating system and application development. Statistics has shown that android languages in current mobile market. Android and iOS is the and iOS has held their leading position in current mobile most leading representative as the whole of current market. Developing application in different platforms has generated market as shown in Figure 1 below. Peoples tend to be many problems; a lot of time, cost and man power is needed if prompted by the current trends and the total applications there is no significant porting work for cross platform several available in each platform. In order to avoid re- mobile devices are propose For example- XMLVM, implementing the same application diversely, frameworks Phonegap, PhoneXml, DragonRad and RhoMobile, each with and tools such as XMLVM, Phonegap, PhoneXml, their own strength.

  • Master's Thesis
    Master's Thesis Two years International Master’s Programme in Computer Engineering Platform Independent Connections to the Internet of Things MA level, 30 credits Sandeep K.C. Platform Independent Connections to the Internet of Things Sandeep K.C. 2014-08-22 ii Platform Independent Connections to the Internet of Things Sandeep K.C. 2014-08-22 Abstract In the past few years, technology has been changing by leaps and bounds, within which a new topic has emerged as Internet of Things. These things serve as sensors/actuators, connected to the Internet and enabled to communicate with each other simultaneously in a P2P distributed manner. The sensors/actuators sense and generate contextual data in their surroundings in order to enable real- time context-aware behavior that make them more personalized and intelligent. This contextual information may be useful for human purposes like environment monitoring, home surveillance, elderly care, safety, security surveillance, etc. Moreover, smart mobile devices with incredible features have become hugely popular, the use of the Internet of Things would be much handier using smartphones to interact with sensors and also to generate information with its decorated sensors. The main aim of this thesis work is to create an extension for an add-in layer of the Internet of Things (SensibleThings Platform) architecture that adds functionalities like querying UCI value within the platform, connecting different mobile devices regardless of programming language, which has been done using the REST protocol. Furthermore, the intention is to build a P2P connection between the Java coded SensibleThings platform to a non-Java platform, i.e.
